Bauteilscomponent
Die Erfindung betrifft ein Verfahren zur Herstellung eines drucktragenden Bauteils mit einem Reduzierstück, insbesondere für Armaturen-, Pumpen-, Wärmetauscher-, Verteiler- und Filtergehäuse. Derartige Bauteile finden in unterschiedlichen Bauformen aus verschiedenen Werkstoffen Verwendung. Ferner finden Armaturen- oder Filtergehäuse u. a. Einsatz im Vakuum-, kryotechnischen und Hochtemperaturbereich. Dabei sollen im kryotechnischen Einsatzbereich die Gehäuseteile möglichst gleichmäßige Wandungen aufweisen, wobei in der Kryotechnik häufig Bauteile mit einer Vakuumisolierung verwendet werden. Die Vakuumisolierung muß die Erzeugung und Aufrechterhaltung des Vakuums gewährleisten, so daß nur drucktragende Bautei- Ie aus diffusionsdichten Werkstoffen (geschmiedet, ge- presster Werkstoff; sauber) verwendet werden können.The invention relates to a method for producing a pressure-bearing component with a reducer, in particular for fittings, pump, heat exchanger, distributor and filter housing. Such components are used in different designs of different materials use. Furthermore find fitting or filter housing u. a. Use in vacuum, cryogenic and high temperature range. Here, in the field of cryogenic application, the housing parts should have as uniform as possible walls, wherein in the cryogenics often components are used with a vacuum insulation. The vacuum insulation must ensure the generation and maintenance of the vacuum, so that only pressure-bearing components made of diffusion-proof materials (forged, pressed material, clean) can be used.
An diese drucktragenden Bauteile sind je nach Einsatzgebiet sicherheitstechnisch hohe Anforderungen zu stellen. Wird beispielsweise eine Stellarmatur für ein Kraftwerk verwendet, unterliegt das drucktragende Armaturengehäuse den Richtlinien gemäß TRD oder CE-Norm AD- 2000. Damit die drucktragenden Bauteile diesen Anforderungen genügen, müssen an kritischen Stellen zerstörungsfreie Überprüfungen, z. B. mittels Röntgen, Ul- traschall oder durch Rissprüfungen erfolgen, um sicher- zustellen, daß keine Materialfehler vorliegen. Dabei ist die Durchführung der Überprüfung aufgrund der komplexen Geometrie der Bauteile aufwendig und zeitintensiv. Es ist daher Aufgabe der Erfindung, ein Verfahren zur Herstellung eines drucktragenden Bauteiles mit einem Reduzierstück bereitzustellen, bei dem die Überprüfung auf Fehlerfreiheit vereinfacht ist.Depending on the field of application, high demands are placed on these pressure-bearing components in terms of safety. For example, if a control armature is used for a power plant, the pressure-bearing fitting housing is subject to the guidelines according to TRD or CE standard AD-2000.

Es wird zunächst auf die Figuren 1 und 2 Bezug genommen. Gezeigt ist ein Ventil mit einem Eingang 12 und einem Ausgang 14, die an Rohrleitungen angeschlossen werden können. Der Eingang 12 und der Ausgang 14 des Ventils sind durch einen Strömungskanal miteinander verbunden, der mittels eines Ventilkegels 8 geöffnet und verschlossen werden kann, wobei die Ventilsteuerung zum Verschieben des Ventilkegels 8 zwischen der geöffneten und der geschlossenen Position nicht dargestellt ist.Reference is first made to FIGS. 1 and 2. Shown is a valve with an input 12 and an output 14, which can be connected to pipelines. The inlet 12 and the outlet 14 of the valve are interconnected by a flow channel which can be opened and closed by means of a poppet 8, the valve control for shifting the valve plug 8 between the open and the closed position is not shown.
Das Ventil selbst besteht aus einem Reduzierstück 2 zylindrischer Grundform, an das an einer Verbindungsstelle 16 ein Krümmer 4 angefügt ist. Das Krümmerende 10 am anderen Ende des Krümmers 4 kann mit dem Ventil- kegel 8 geöffnet oder geschlossen werden.The valve itself consists of a reducer 2 cylindrical basic shape, to which at a junction 16, a manifold 4 is added. The manifold end 10 at the other end of the manifold 4 can be opened or closed with the valve cone 8.
Das Reduzierstück 2 bildet ferner den Eingang 12. Außerdem ist an dem Reduzierstück 2 an einer Verbindungsstelle 18 ein T-Stück 6 derart angefügt, daß der an dem Reduzierstück 2 angefügte Krümmer 4 im Inneren des T-Stücks 6 angeordnet ist.The reducer 2 further forms the input 12. In addition, a T-piece 6 is attached to the reducer 2 at a junction 18 such that the attached to the reducer 2 manifold 4 is disposed in the interior of the T-piece 6.
Somit kann ein Stoffstrom bei geöffnetem Ventilke- gel 8 durch den Eingang 12 zum Krümmerende 10 des Krümmers 4 entlang und dann weiter durch das Innere des T- Stücks 6 zum Ausgang 12 weiterstömen.Thus, with the valve plug 8 open, a flow of material can continue through the inlet 12 to the manifold end 10 of the manifold 4 and then further through the interior of the T-piece 6 to the outlet 12.
Dabei sind das Reduzierstück 2, der Krümmer 4 und das T-Stück 6 aus einem hochreinen Stahl gefertigt, der keine Seigerungszonen aufweist und beispielsweise elek- troschlackeumgeschmolzen (ESU) ist, wobei das Material anschließend geschmiedet oder verpreßt wurde.The reducer 2, the manifold 4 and the T-piece 6 are made of a high-purity steel which has no segregation zones and is, for example, electroslag remelted (ESR), the material subsequently being forged or pressed.
Im folgenden wird nun anhand der Figuren 3 bis 8 die Fertigung und Überprüfung der in Fig. 1 und 2 ge- zeigten Ventile beschrieben.The production and checking of the valves shown in FIGS. 1 and 2 will now be described below with reference to FIGS. 3 to 8.
Das Reduzierstück 2 wird mittels Drehen, Fräsen, Schmieden, Pressen oder Feinguß aus einem Rohling 20 gefertigt, der ein Schmiederohling oder ein abgelängter Abschnitt eines Rohres sein kann. Dabei weist der Roh- ling 20 eine zylinderförmige Grundform mit einem zentralen Durchgang auf, so daß der Rohling 20 vor seiner weiteren Verarbeitung problemlos auf Fehlerfreiheit (Ungänzen) überprüft werden kann. Dabei kann die Überprüfung des Rohlings auf Fehlerfreiheit (Ungänzen) mit- tels Verfahren zur zerstörungsfreien Werkstoffprüfung, vorzugsweise durch eine Ultraschall-Volumenprüfung unter Verwendung eines Senkrechtprüfköpfes erfolgen.The reducer 2 is made by means of turning, milling, forging, pressing or precision casting from a blank 20, which may be a forging blank or a cut-to-length section of a pipe. In this case, the blank 20 has a cylindrical basic shape with a central passage, so that the blank 20 can easily be checked for freedom from defects (discontinuities) before its further processing. The check of the blank for correctness (discontinuities) can Nels method for non-destructive material testing, preferably carried out by an ultrasonic volume test using a vertical Prüfköpfes.
In einem nächsten Schritt (siehe Fig. 4) wird aus dem Rohling 20 das Reduzierstück 2 mittels Drehen, Fräsen, Schmieden, Pressen oder Feinguß gefertigt. Dabei weist das Reduzierstück 2 in seiner endgültigen Form einen ersten und zweiten Anschlußabschnitt 24, 26 mit großem Durchmesser auf, die sich gegenüberliegen, und einen Anschlußabschnitt 22 mit kleinem Durchmesser auf. Der erste Anschlußabschnitt 24 mit dem großen Durchmesser bildet später den Eingang 12 des Ventils und kann mit einer Rohrleitung verbunden werden, während der zweite Anschlußabschnitt 26 mit großem Durchmesser dazu dient, eine Verbindung mit einem T-Stück 6 herzustellen. Der Anschlußabschnitt 22 mit dem kleinen Durchmesser dient zur Verbindung des T-Stücks 2 mit einem Krümmer 4. Dabei ist der Anschlußabschnitt 22 mit dem kleinen Durchmesser verlängert gegenüber dem zwei- ten Anschlußabschnitt 26 mit dem großen Durchmesser ausgebildet.In a next step (see FIG. 4), the reducer 2 is produced from the blank 20 by means of turning, milling, forging, pressing or precision casting. In this case, the reducer 2 has in its final form a first and second connecting portion 24, 26 of large diameter, which face each other, and a connecting portion 22 with a small diameter. The first large diameter port portion 24 later forms the inlet 12 of the valve and may be connected to a conduit while the second large diameter port portion 26 serves to connect to a T-piece 6. The small-diameter terminal portion 22 serves to connect the T-piece 2 to a manifold 4. At this time, the small-diameter terminal portion 22 is elongated with respect to the second large-diameter terminal portion 26.
So kann die Verbindungsstelle 16 zwischen dem Anschlußabschnitt 22 mit dem kleinen Durchmesser des Reduzierstücks 2 mit dem Krümmer 4 durch Schweißen ver- bunden werden. Diese Schweißnaht im Bereich der Verbindungsstelle 16 ist leicht zugänglich und kann mittels Verfahren zur zerstörungsfreien Werkstoffprüfung, vorzugsweise durch eine Ultraschall-Volumenprüfung unter Verwendung eines Senkrechtprüfköpfes geprüft werden. In einem nächsten Schritt wird der mit dem Reduzierstück 2 verbundene Krümmer 4 in das Innere des T- Stücks 6 derart eingeführt, daß es im Inneren des T- Stücks 6 angeordnet ist. Anschließend wird an der Verbindungsstelle 18 zwischen dem Reduzierstück 2 und dem Krümmer 4 mit dem T-Stück 6 durch Schweißen eine Verbindung zwischen den zweiten großen Durchmessern des Reduzierstücks 2 und dem T-Stück 6 hergestellt.Thus, the joint 16 between the small diameter portion of the reducer 2 can be connected to the manifold 4 by welding. This weld in the region of the connection point 16 is easily accessible and can be tested by means of a non-destructive material testing method, preferably by an ultrasonic volume test using a vertical test head. In a next step, the manifold 4 connected to the reducer 2 is inserted into the interior of the T-piece 6 so as to be located inside the T-piece 6. Subsequently, at the junction 18 between the reducer 2 and the Manifold 4 with the tee 6 by welding a connection between the second large diameters of the reducer 2 and the tee 6 made.
Dabei kann die Verbindungsstelle 18 zwischen dem Reduzierstück 2, dem Krümmer 4 und dem T-Stück 6 mittels Verfahren zur zerstörungsfreien Werkstoffprüfung, vorzugsweise durch eine Ultraschall-Volumenprüfung unter Verwendung eines Senkrechtprüfköpfes erfolgen, da die Verbindungsstelle 18 zum Reduzierstück 2 mit dem Krümmer 4 und dem T-Stück 6 leicht zugänglich ist.In this case, the connection point 18 between the reducer 2, the manifold 4 and the tee 6 by means of non-destructive material testing, preferably by an ultrasonic volume test using a vertical probe done, since the junction 18 to the reducer 2 with the manifold 4 and the T-piece 6 is easily accessible.
Es wird nun auf die Fig. 9 und 10 Bezug genommen.Reference is now made to FIGS. 9 and 10.
In einem weiteren Schritt wird das Ventil mit einer Ummantelung 28 versehen, sodaß das Ventil doppel- wandig ummantelt ausgebildet ist und der Zwischenraum zwischen dem Ventil und der doppelwandigen Ummantelung 28 auch auf Leckagen überwacht werden kann oder Raum für eine Vakuumisolierung gegeben ist. Dabei besteht die Ummantelung 28 aus zwei Hälften, die an das Ventil angefügt werden und entlang von Verbindungnähten ver- schweißt werden. Dabei weist die Ummantelung 28 eine Vielzahl von Stützen 30 auf, die der Befestigung und/oder Justierung an des Außenmantels des Ventils dienen.In a further step, the valve is provided with a jacket 28, so that the valve is formed with double-walled casing and the space between the valve and the double-walled casing 28 can also be monitored for leaks or there is room for vacuum insulation. In this case, the sheath 28 consists of two halves, which are attached to the valve and welded along connecting seams. In this case, the sheath 28 on a plurality of supports 30, which serve the attachment and / or adjustment to the outer jacket of the valve.
Die Verbindungsnähte zwischen dem Teilen der Um- mantelung 28 können mittels Verfahren zur zerstörungsfreien Werkstoffprüfung, vorzugsweise durch eine Ultraschall-Volumenprüfung unter Verwendung eines Senkrechtprüfkopfes überprüft werden, sodaß sichergestellt ist, daß auch die Schweißnähte der Ummantelung 28 feh- lerfrei sind. Um die Überprüfung der Schweißnähte zu erleichtern, sind die Stützen 30 in Bezug zu den Schweißnähten derart angeordnet, daß die Schweißnähte zurückspringen und nicht im Bereich der Stützen 30 angeordnet sind. Anschließend wird der Ventilkegel 8 mitsamt der Ventilsteuerung montiert, sodaß ein doppelwandiges Ventil für höchste Sicherheitsanforderungen zur Verfügung steht. The connecting seams between the parts of the sheathing 28 can be checked by means of a non-destructive material testing method, preferably by an ultrasonic volume test using a vertical test head, so as to ensure that the weld seams of the sheath 28 are also free of errors. In order to facilitate the inspection of the welds, the supports 30 are arranged with respect to the welds such that the welds spring back and are not arranged in the region of the supports 30. Subsequently, the valve plug 8 is mounted together with the valve control, so that a double-walled valve is available for the highest safety requirements.
